Indeed, they are. At least those integrated into the system. I found that whenever I implement some service, I need special things for monitoring and restarting it anyways. It is really not hard doing your own service manager that then just gets started by init.

I agree to that. Nothing important is dependent on systemd, except maybe udev. But even that can be replaced with reasonable effort if there is enough motivation. And Gentoo already has a replacement with eudev. Trying an "embrace and extend" move on Linux is ultimately futile. Sure, you can make a lot of people waste a lot of time, but that is it.

This fight is not over. From all the error-reports on the mailing-lists of the distros that have started using systemd, at the moment the only thing the opponents need to do is watch the fireworks and occasionally remind people that there are superior init systems and service managers.

We will see how this plays out. I expect there will be some rather quiet reversal in several distros in the not too distant future. And if not, there is no real need to have a Linux kernel under a GNU system. I also see no really serious problems keeping SYSVinit going. The only hurdle seems to be udev, but there is eudev and if that does not work out, I never really had any need of udev in the first place. Overall, it probably cost me more time than it saved. I may just go back to ultra-reliable static device files.

Just proves my point: You have no clue what you are talking about. The observation of intelligence in humans is an interface observation, it is completely unclear whether it gets created there and how that would work if so.

Of course if you assume physicalism, then you can deduce physicalism. That is circular reasoning however. The scientifically sound answer to "Does the brain generate human intelligence?" is "We do not know.". Also note that even if that were the case, it would not at all "prove" that AI is possible. It would just mean that biologically generated intelligence is possible, but with a few quirks, like consciousness and free will and a rather low average level of intelligence.
